1) A 9-year bond with a face value of 1000 dollars is redeemable at twice par and earns interest at 10 percent convertible semiannually. If the yield rate is 7.5 percent convertible semiannually, find the book value two months after the payment of the 13th coupon. (Recall that we use simple interest for points in time between coupon payments.)

2) Suppose that a 12-year bond with a face value of 2500 dollars is redeemable at par and pays semiannual coupons that increase by 1.6 percent per coupon. If the last coupon is for 80 dollars and the yield rate is 7.7 percent convertible semiannually, what is the book value of the bond immediately after the 11th coupon is paid?
